Atlantis, built thousands of years ago by the highly evolved Ancients, is home base for an elite expedition from Earth. These courageous military commanders and scientists leap through the city's Stargate to explore the wondrous Pegasus galaxy and battle the treacherous Wraith, who seek control of Atlantis -- at any cost.

A Wraith hive ship arrives in orbit above Atlantis. In the cloaked city below, everyone is stunned when Michael radios down with an unnerving request: He wants to negotiate an alliance.
